iivi'rrring to the (irn\\'ing.\:--l i; the spring: irv of which the body of H1 guard 1 i'mnpowii, (siumn iu Fig. i in 1il( fire-1: sir-1 m" ordinary' construction, the guard is formed of one continuous piece of spring-wire. The frame and longitudinal wires are of the same stock, the size and tension of each and the tension of the guard as a whole depending solely on the choice of stock. The guard is as light as possible, consistent with strength; in its detached condition itsflat shape economizes space, its own tension holds it in place, and it can be'rapidly attached to and detached from the car. The spirals 2 serve to keep the wire members equally spaced, and their spring action adds to the cushion effect of the yielding wire elements of the guard. The longitudinal frame wires 5 serve mainly to connect the separate wire elements and add strength to the whole guard, but in addition they assist in preventing any one or more wires receiving a shock that would dcform theguard. Moreover, the longitudinal wires distribute the tension and bring the guard into action as a whole, thus producing a resilient cushion action. The space be tween neighboring wires should be such that no portion of a persons anatomy could possibly get through. As said above, when it is desired to attach a trailer, etc, the guard may. have its central portion detached from the rest/of the'frame wire. in this case, deg

taching the clip-hooks frb in the upper bumper rod 7, the part 13 straighteifs out ii at under the released tension, aml swings" pix;- otally on rod 8 out of harms way under the car. i

Having thus fully described andillustrated my invention, what I clan 1 is 1. A bumper guard formt d of one continuous piece of spring wire provided with means for rapidly attaching to and detaching from the guard adapted to conforiu automatically to the shape of the bumper and hold itself in place by its own tension.

2. A bumper guard formed of one continuous piece of spring wire provided with means for rapidly attaching to and detaching from the guard, having its upper and lower edges formed into double spiral spring, SUbSULD-z tially as set forth.

3. A spring bumper guard, having its upper and lower edgesnformgd into doube s iral springs, longitudinal framewires inclosed by said springs, and means for detachably holding the guard in operative relation on the car.

{L A detachable spring 'bumper guard, having its upper and lower edges doubled over to form spiral springs, a loop fashioned in the guard-wire intermediate the up er and lower s ring edges, and longitudina wires loosely mclosed by the springs, substantially as set forth. 5. A spring bumper-guard, having its upper and lower edges formed into ,doub

spiral springs, longitudinal frame-wires in c osed by said springs, and oh -hooks on-said wires for detacha bly holding t he guard in operative relation on the car.

6. A detachable spring wire bumper-guard having its upper and lower edges doubled over to form spiral springs, a plurality of loops formed in the guard-wire intermediate I the up or and lower spring edges, and longitudina wires loosely inclosed by the springs I and loops, substantially as set forth.

7. In a bumper-guard, the comblnation'of a number oi spring wire elements whose upper and lower edges are doubled over to form spring loops, loops fashioned in the wire ele= ments intermediate the doubled-over edges, longitudinal wires inclosed by the spring and intermediate loops, rods fastened to the upper and lower sides of the bumper, andmeans detachably connecting the guard to the bumper rods, substantially as set forth.

8. A bumper-guard formed of spring wire, continuous up to the middle ortion, said middle portion being detachab e froin the rest of the guard, and adapted to swing pivotally on the guard supporting rod, substantially as set forth. I

9. The combination in a bUl1]]])l-gllf1.l'd, of a series of spring wire members raving loops fashioned in their ends and intermediate be tween the ends, iongitiulinal supporting and strengthening vvires passing through .the loops, rods attached to'the top and bottom of the car platform, bracltetsattzwhed to the curved ends of the bumper and engaging the doubled-over ends of the guard, substantially
